Got caught in a thunderstorm three times, hypothermic twice, hailed on twice... Not my initial idea of a good time, but now that I am safely back, I can say that I loved it.

Climbed the ridge in two days from Zugspitze to Alpspitze using the hut on the ridge. It takes more time then we were expecting, but with the time and the weather on our side we decide to take it easy and make it in two days. Nice tour, sometimes a little airy...

Ropeway to Kreuzeckhaus. Next morning Alpspitze via Schöngänge and SE ridge, over to Jubiläum ridge to bivy hut. Clouds fell in that evening, but the morning brought the sun's splendor back again, with -16°C inside and -18°C outside the hut. Continued to Zugspitze bypassing several steep ridge sections using snow gullys on the S side of the ridge. Arrived at summit just 20 minutes before the last ropeway went down.
Would guess its better done in winter when loose gravel is snow-covered than in summer, and - I would never do it upside down, starting from the top (Zugspitze).

perfect weather, warm and clear (views on Grossglockner, Marmolada, Piz Bernina) but for average climbers as me and Frank a very demanding day: 10 h walk, many exposed and non fixed scrambling. Often the red spots can hardly be seen any more so you have to look very carefully for the route.

We took the Alpspitzbahn to Osterfelderkopf(2050m), climbed the Alpspitze via the Eastridge, this route takes one hour longer compared to the Northridge but provides you with a breathtaking look down in the Grieskar.

Routefinding on the ridge was generally no problem. Only finding the start of the klettersteig to bypass Hochblassen took some time. Most technical part during the first day was the Vollkarspitze, but route is well secured. Had excellent weather the first day, sunny, no wind.

Second day started out sunny, but it started raining when we past the Innere Höllentalspitze, the most technical portion of the second day, this part is not secured all the time, and the rain made us decide to rope in. We took the Zugspitzbahn down to Eibsee (and payed 25 € each for it!?)

Average time between Alpspitze and Zugspitze is 10 hours, with the bivac hut at 4 hours from Alpspitze.

P.S. We left half a bottle of Schnapps behind in the hut, cheers to the first one to get there after us;-)

We did this as a 2 day trip with a small tent (see posted picture). First day ascent through the nice 'Hoellental' up to Zugspitze and approx. 2 hours into the 'Jubilaeumsgrat'. Had to carry lots of stuff (íncl. water since the ridge was absolutely dry that summer) but enjoyed a nice bivouc with cooking and wine on the ridge. Next day we continued quite relaxed into the route - but only until a 'jogger' with leggins and running shoes overtook us. I'll use the latter equipment next time ;-)

PS: repeated that in opposite direction (Osterfelder Kopf - Alpspitze - Zugspitze) on July 20th, 2005. Takes a bit longer than Zugspitze - Alpspitze since going more up than down. You need to hurry to catch the cable car on Zugspitze and also should use the first cable car to Osterfelderkopf in the morning. In order to be faster then 8 hours you should speed up.

PS: Looking for a partner to do it in winter - no running boots then...

After getting up to Zugspitze with the first cable car we started at 7.30 a.m.

The snow and weather conditions were quite good (fog and wind only for the first two hours). Getting up Vollkarspitze with backpack and plastic boots was a bit exhausting. We had our ski with us and left the ridge at Grieskarscharte to ski down to Bernadein (Garmisch ski area).

Route Climbed: Full traverse as described in Log Date Climbed: June 6-7? 1983

First Alpine trip I ever did with a group of other climbers while we were stationed nearby. We tented at the bivouac and had a really remarkable time one gets all the feeling of being high up witout alot of hard climbing.
